Publication of Beyond intergovernmental relations in federal systems: the concept of intergovernmental law
In federal systems, irrespective of the official division of powers, the development and implementation of public policy increasingly require the input of various orders of government. Concerted action is an everyday phenomenon in wide ranges of domains, such as health care, immigration, transportation, environmental protection, public safety, and pandemic management. Countless studies have explored intergovernmental interaction in federal systems, both from a political science and policy perspective. Faced with federal realpolitik, law is often considered to be ‘beside the point’. While constitutional law provides a backdrop (particularly the division of powers, courts, and second chambers), law is otherwise largely a blind spot of federal studies. Yet, in democracies founded on the rule of law, all public action must, at some point, be grounded in law, or at least accountable to law. This is also true of federal democracies. The production and implementation of law in complex intergovernmental contexts are oddly understudied, as are the processes of accountability for intergovernmental executive action.
To shed light on the various ways through which legal norms, principles, processes and institutions shape federal governance, this paper introduces the concept of Intergovernmental Law (IGL). Professor Poirier posits that IGL has three main components. Upstream, it is composed of constitutional norms and institutions that shape intergovernmental action. Downstream, IGL includes processes of judicial review and parliamentary scrutiny of administrative and executive actions taken in an intergovernmental context. Midstream, it comprises specific toolboxes of legislative and executive law-making devices that help structure interactions and create complex normative networks.
Cheryl Saunders’ scholarship in domestic and comparative constitutional law informs almost every aspect of the overarching concept of intergovernmental law. This article is a tribute to Cheryl’s invaluable contribution to federal studies, notably her efforts in shedding light on the role of law in shaping federal theory and practice.

Discussion: Postcolonial Federalism: tracing colonial state-formation in the Global South
Join us and the McGill Centre for Human Rights and Legal Pluralism for a discussion with Shahal Khoso, Doctoral Candidate at the Pompeu Fabra University (Barcelona) and visiting scholar at the Peter MacKell Chair in Federalism, on his paper, "Postcolonial Federalism: tracing colonial state-formation in the Global South," winner of the First Prize of the Baxter Family Competition on Federalism (2023) and of the Ron Watts Award (International Association of Centers for Federal Studies, 2023).
Details:
- Wednesday, February 21, 2024 from 13:00 - 14:30 (ET)
- McGill Faculty of Law, New Chancellor Day Hall, Room 202
Description:
Why do federations from the Global South operate differently from Western democratic federations? Is it important to see the socio-historic pattern in which they were created? Was federating a choice or the only option left by the colonial administration for some ex-colonies? To answer these questions, this paper discusses the different types, ideals, and values of federalism considering existing literature. This paper dissects the British colonial venture in Nigeria, India, Pakistan, and Malaysia, and their historical journeys towards federalism, comparing and analysing if these postcolonial federations are in line with Alfred Stepan’s categories of the genesis of federations. This paper proposes a universe of cases that bode multiple commonalities and a pattern that theories of federalism have overlooked. Postcolonial Federalism develops a new lens to scrutinise the complex relationship between colonialism and federalism, especially for its proposed cases, highlighting their unique structuring through colonial socio-political engineering. Moreover, it argues that the creation of these federations was carried out with complete disregard for the existing linguistic, ethnic, cultural, and religious cleavages for the feasibility of colonial administration, leaving federalisation as the only alternative to gain sovereignty. This paper acts as a safeguard against the notion of the federal arrangement only being a product of democratic, liberal, and contractual phenomena.

Comparative Federalism and Covid-19: Combating the Pandemic
The Chair is happy to announce the publication of Nico Steytler (ed), Comparative Federalism and Covid-19: Combating the Pandemic (London: Routledge, 2021): With case studies from 19 federal countries, this collection explores the core elements of federalism that came to the fore in combatting the pandemic: the division of responsibilities (disaster management, health care, social welfare, and education), the need for centralisation, and intergovernmental relations and cooperation.
The authors adopt a multidisciplinary approach to question whether federalism has been a help or a hindrance in tackling the pandemic. Johanne Poirier and Jessica Michelin contributed the chapter on Canada, which is entitled “Facing the Coronavirus Pandemic in the Canadian Federation: Reinforced dualism and muted cooperation?”.
Publication of Canadian Federalism and Its Future / L’avenir du fédéralisme canadien
Nearly four years after the “Canada 150” conference, we are happy to announce that the collections are available in English and in French from McGill / Queen's University Press and from les Presses de l'Université Laval (2020).
"The time is ripe to revisit Canada's past and redress its historical wrongs. Yet in our urgency to imagine roads to reconciliation with Indigenous peoples, it is important to keep in sight the many other forms of diversity that Canadian federalism has historically been designed to accommodate or could also reflect more effectively. Canadian Federalism and Its Future brings together international experts to assess four fundamental institutions: bicameralism, the judiciary as arbiter of the federal deal, the electoral system and party politics, and intergovernmental relations. The contributors use comparative and critical lenses to appraise the repercussions of these four dimensions of Canadian federalism on key actors, including member states, constitutive units, internal nations, Indigenous peoples, and linguistic minorities. Pursuing the work of The Constitutions That Shaped Us (2015) and The Quebec Conference of 1864 (2018), this third volume is a testimony to Canada's successes and failures in constitutional design. Reflecting on the cultural pluralism inherent in this country, Canadian Federalism and Its Future offers thought-provoking lessons for a world in search of concrete institutional solutions, within and beyond the traditional nation-state."
L’avenir du fédéralisme canadien (available in open access)
Publication of Cinquante déclinaisons de fédéralisme: Théorie, enjeux et études de cas
This French-language collection was co-edited by our postdoctoral researcher, Dave Guénette.
Cette collection de 50 brèves contributions de spécialistes internationaux "propose un apport d’une grande ampleur tout en se voulant le plus exhaustif possible. Il s’agit d’un ouvrage de référence qui expose clairement les concepts que les chercheurs en études fédérales mobilisent, les cadres d’analyse qu’ils emploient ainsi que les spécificités sociopolitiques qu’on observe dans les diverses structures fédérales existantes. Ce livre comprend également un glossaire constitué de cinquante notions clés, toutes définies de manière simple et usuelle. Faisant le point sur les débats contemporains, il a pour vocation d’initier les étudiants, les décideurs et le grand public à ce champ d’études en pleine effervescence."
This collection, published in 2020 by Presses de l'Université du Québec, is available in open access.

Cooperative Federalism and Intergovernmental Relations:
What's Law Got To Do With It?
2019-2022 Research project funded by the Secrétariat du Québec aux relations canadiennes
In 2019-2022, Professor Johanne Poirier will be leading a major research project on intergovernmental relations and cooperative federalism.
The technical ramifications and legal implications of intergovernmental agreements, as well as their implementation, have been generally neglected by jurists. However, cooperative mechanisms crafted by the executives can have undeniable collateral effects on the scope of parliamentary scrutiny over the executive, on judicial review of administrative action and on the balance of federal architecture.
Professor Johanne Poirier will attempt to fill these doctrinal gaps by studying the law that emanates from, structures and affects intergovernmental agreements. She also plans to initiate a form of “catalogue” of cooperative techniques and of the role played by law in structuring them. While the project is focused on cooperative federalism in Canada, it will benefit from a comparative lens: analysing foreign experience being so often the best way of decoding the particularities of one’s own system.
Ultimately, her work harbors significant potential to provide answers to the various components of the Canadian federations on the uncertainties inherent to the modalities of intergovernmental cooperation, on the stability of cooperative mechanisms and on the courts’ responses to them.
